You need to use loop-AES version of losetup in your initrd.
Try copying a statically linked version of losetup to your USB-stick.

 mkdir /stick
 mount -r -t vfat /dev/sdb4 /stick
 /stick/losetup -e AES256 -K /stick/key.gpg -G / /dev/loop0 /dev/sda3
 ^^^^^^^                                    ^^^^

To compile statically linked version of losetup, add this to util-linux
configure comand:

 CFLAGS=-O2 LDFLAGS="-s -static" ./configure
            ^^^^^^^^^^^^^^^^^^^^
